Identify True or False sentences among the following:
(a) Like charges attract each other (T/F)
(b) A charged glass rod attract a charged plastic straw (T/F)
(c) Lightning conductor cannot protect a building from lightning (T/F)
(d) Earthquakes can be predicted in advance (T/F)
(a) False
Like charges repel each other and unlike charges attract each other.
(b) True
A charged glass rod has positive charge on its surface while the charged plastic straw has negative charge on its surface. And unlike charges attract each other therefore the above statement is true.
(c) False
During a lightning, the lightning conductor conducts all the atmospheric charges to the earth directly, leaving the building safe. Hence, the lightning conductor protect a building from lightning.
(d) False
The reason for the earthquake can be known, but no instrument could be invented to detect it till now. Hence, earthquakes cannot be predicted in advance.
